14 MISCELLANEOUS PAPERS. 



Color of body very dilute yellowish-white, segments 4 to 8 of 

 antennae grayish brown. 



Head angular in front, depressed to receive basal segments of 

 antennse; sides straight, about one and one-third times as wide as 

 long; spines on head inconspicuous, except one on inner side of each 

 posterior ocellus. Eyes large, black, not protruding, slightly pilose; 

 facets large. Ocelli approximate, yellow, with brownish-red crescents. 

 Mouth-cone short, blunt, tipped wdth black; maxillary palpi 3-seg- 

 mented; labial palpi 2-segmented. Antennse, 8-segmented, slender, 

 about two and three-fifths times as long as the head ; segments 3 and 4 

 distinctly constricted into a handle at the base. Color of segments 

 1, 2, and 3 white, faintly tinged with yellow, outer half of segment 

 3 darker; remaining segments grayish brown, except apices, which 

 are transparent white. A forked sense-cone on dorsal side of seg- 

 ment 3, a similar one on ventral side of segment 4, and two simple 

 sense-cones on each side of segments 5 and 6, near apex. Spines 

 pale and inconspicuous. 



Prothorax only a little wider than the head, constricted in the 

 middle; two long, prominent spines on each posterior angle, no 

 visible spines on posterior margin, but four or five short, slender, 

 inconspicuous spines on lateral margins extending to anterior angles. 

 Mesothorax largest, sides of Serothorax broadly and evenly rounded. 

 Legs long and slender, concolofous with body, very light yellowish- 

 white; spines on hind tibiae alone visible. Wings present; forewings 

 broadest at basal third, pointed at ends, all veins conspicuous to end 

 of wings. Spines arranged as follows: Costa with about eighteen 

 very long, strong spines, much longer than is usual in this genus; fore 

 longitudinal vein with eight spines, six at base and two at apex; 

 hind longitudinal vein with eight regularly placed spines, beginning 

 where basal group on fore vein ends; anterior fringe very light; 

 posterior fringe long ; both fringes present only on apical half of wing. 

 .Wings concolorous with body, very light yellowish white. 



Abdomen long and slender; spines conspicuous only on last two 

 segments; a comblike arrangement on posterior margin of segment 8. 



Described from one female specimen from flowers of California 

 buckeye {^Esculus calif ornica) , June 6, 1910, San Jose, Cal. (P. R. 

 Jones.) Male unknown.
